wouldn't work in Europe (since the 2 sides of the 230V mains are
not balanced about ground), and anyway AFAIK making the protecive
ground wire carry any current under normal conditions is totally
forbidden.
Right. Like I said, the chassis was bonded to neutral, not neutral
bonded to ground. I guess it's the same situation as an 120V appliance
whose chassis is bonded to the neutral line in a 2-wire, non-grounded
plug.
Though, ground carrying some current isn't all that uncommon. There are
plenty of things that have a non-trivial leakage current (eg, MOV or
other surge protector devices). I've seen some computer equipment with
warnings about having a "high leakage current".
Yes, you're right. I am sure there;s a limit to the mazximum permitted
leackage current. It's not zero, but ti's probably not that high either.
Mins filters often have cpaciaotrs from the power-carrying wires to
ground, and they will pass some AC current.
